STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Reissued Letters Patent No. 11,100, datedAugust 5, 1890,

Original No. 376,015, dated January 3, 1888. Application for reissuefiled June 13, 1890. Serial No. 355,905.

To all whom it may concern.-

Be it known that LTHoMAs F. SHERIDAN, a citizen of the United States,residing at Springfield, in the county of Sangamon and State ofIllinois, have invented certain new and useful Improvements in Stem\Vinding and Setting \Vatches; and I do hereby declare the follow-' ingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of thisspecification.

My invention relates to that class of Watches provided with stem-driven.trains.

Heretofore in watches of this class stemdriven winding and settingtrains have been designed which are either normally engaged with thedial-wheels or the windingwheel. WVhen the stem-driven train has beennormally engaged with the winding-wheel, a positive connection wasnecessary between the stem-driven train and the stem-arbor to effect thesetting engagement to the stem driven train and the dial-wheels.Consequently, as the stem-arbor was a part of the movement, the latterwas not interchangeable in all styles of cases.

My invention has for its object to provide a watch-movement with awinding and handsetting train of such construction that the movement maybe used in any style of watchcase of either the lever or pendant-settingclass. In myimproveddevicethestem-driven train is normally in engagementwith the winding-wheel, but is adapted to be placed in engagement withthe dial-wheels by the action of a spring controlled by a setting-lever,or when placed in a watch-case provided with a longitudinallymovablestem-arbor said train can be permitted to assume either of the aforesaidengagements, according to the position in which the stem-arbor may beplaced. My invention therefore renders the movement independent of anyparticular style of watch-case, while at the same time permitting it tobe used in a watch-case of either the lover or pendant setting class.

In the accompanying drawings, Figure l is a plan view of awatch-movement embodying my invention with the stem-driven train inengagement with the winding-wheel. Fig. 2

is a similar view of the same with the stemdriven train in. engagementwith the dialwheels. Figs. 3 and stare detail views of portions of thewinding and setting mechanism. Fig. 5 is a plan view of the side of awatch opposite to that shown in Figs. 1 and 2, and showing thesetting-lever in position to allow a normal engagement of thestem-driven train with the winding-wheel. Fig. 6 is a transverse sectionof the movement and watchcase on the line 6 6 of Fig. 1.

In the drawings, A denotes the center band of a watch-case, which isprovided with a pendant a.

B is the pillar or lower plate of a watchmovement, said plate beingfitted or secured to the rim of said case in the usual manner.

\Vithin the pendant a is a stein-arbor 0, provided at its outer end witha corrugated cap or crown O, the inner end of said stemarbor having anaxial engagement with the pinion I), which is journaled in a suitablebearing on the lower face of the plate B, and which has its toothedperiphery extended through an opening I) in said plate, where it engagesthe toothed wheel E, pivoted to said plate by the screw 6, so that saidWheel E can be rotated in either direction by rotating the stem-arbor.

On the upper end of the screw 6 is pivoted a yoke F, to the lower faceof the free end of which is journaled a spur-wheel G, which is in gearwith the wheel E, and which by the os cillation of said yoke upon itspivotalbearing may be moved into or out of engagement with thewinding-wheel H, which is attached to the mainspring or barrel-arbor 'n,or into or out of engagement with the wheel K, which latter isconstantly in gear with one of the dial-wheels. '7

To the plate Bis secured a springf which operates normally to hold saidyoke in such position as to cause the spur-wheel G of the stem driventrain to engage the windingwheel H, as shown in Fig. 1.

On the lower surface of the plate B is fitted a slide-bar 2', the outerprojecting end a" of which enters a recess in the pinion D. The saidslidebaris provided with a laterally-projecting arm 2' carrying a pin 2'which extends through an opening I) in the plate B,

in position to engage the end or locking-angle f of a lug f on the yokeF.

In a suitable recess on the lower face of the plate B is a spring Z,provided with a broad head or end L, the said spring being secured tosaid plate by the pivot-screw Z .Also pivoted to the lower face of theplate B is a setting-lever Z, so arranged relatively to the end L of thespring Z as to engage the said end or head, as shown in Figs. 1 and 2,or to be disengaged therefrom, as shown in Fig. 5. 4

As hereinbefore stated, the gear-wheel G of the stem-driven train isnormally held in engagement with the winding-wheel H by the springf whenthe spring Z and the lever Z are in the positions in Fig. 5. The. springZ is of greater strength than the spring f,

I as will be evident from the relative sizes of said springs asrepresented in the drawings, and when the setting-lever Z is turned intopOSltlOl'l to engage the end or head L of the spring Z, and the saidspring is thus placed under tension, its strength will be sufficient toovercome the stress of the spring f, and thus, through the slide-bardand its pin i acting on the lugf of the yoke F, the said yoke will beoscillated to throw the spurwheel G out of engagement with thewindingwhecl H and into engagementwith the wheel K of the dial-train.Thusit will be seen that the stem-driven train, which is normally heldin engagement with the Winding-Wheel H by the spring f, may be thrownout of engagement with the said winding-wheel and into engagement withthe dial-train by moving the setting-lever Z from the position shown inFig. 5 to the position shown in Figs. 1 and 2; or, in other words, thestemdriven train may be disengaged from the winding-wheel H and throwninto engagement with the wheel K of the setting or dial train by causingthe setting-lever Z to engage the head L of the pivoted spring Z, thusplacing said spring under tension and causing it to overcome the stressof the spring f Thus, when the movement is out of its case during theprocess of timing and adjusting, or when the movement is applied to acase not having a longitudinallymovable stem -arbor, the stemdriventrain may be thrown out of engage ment with the winding-wheel and intoengage ment with the dial-wheels, or vice versa, by the movement of thesaid setting-lever Z. When, however, the movement is applied to a casehaving a longitndinally-movable stemarbor, the setting-lever Z will becaused to engage the end or head L and the spring Z, as shown in Figs. 1and 2, thus causing said spring to overcome the stress of the spring f,as above described, when the stem-arbor is in its outer position,thereby throwing the spurwheel G of the stem-setting train intoengagement with the wheel K of the dial-train. To permit the saidspur-wheel G to assume its normal position of engagement with thewinding-wheel H, the longitudinally-movable stem-arbor is pressedinward, thus forcing inward the slide-bar 1' against the stress of thespring Z, and thereby relieving the pivoted yoke F of the stress of thesaid spring, when the said yoke will be swung by the spring f actingthereon back to its normal. position to throw the spur-wheel G out ofengagement with the wheel K and into engagement with the winding-wheel.It will thus be apparent that by my invention a Watchanovement havingastem-driven winding and setting train is adapted to be applied topendant-setting or lever-setting cases, or, in other words, to caseshaving stem-arbors, which are 'or are not longitudinally movable.

I am aware that there are other devices which accomplish similarpurposesas, for example, a loose pin fitted in the windingpinion tooperate a vibratory lever, which is in turn connected with a swinglocking-bar to operate the train-yoke; but this has its objection, as itrequires several intermediary parts between the stem-arbor and thetrain-yoke. This objection is not found in my invention, which requiresbut one piece between the stem-arbor and the yoke.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. In a stem winding and setting watch, the combination of thestem-driven train, the yoke F, having a projecting lug formed with alocking-angle or end f, the slide-bar i, having the projection 'Z, toenter a recess in the pinion D, and a lateral arm 6 carrying the pin ithe spring Z, pivoted to the pillarplate B, and having the head portionL, and the setting-lever Z, pivoted to the said plate and adapted toengage the head of the said spring, substantially as specified.

2. The combination,.with a stem -(lriven train and its pivoted yoke F,of the slide-bar t', substantially as described, the stem-arbor, and thespring Z, whereby said yoke may be moved to connect or disconnect saidtrain with reference to the winding-wheel, substantially as specified.

The combination, with a stein-driven train, which is provided with apivoted yoke F, having a projecting lugf, formed with a locking-angle orend f of the slide-bar t', having an arm 1 and a projection orpin 1Jexten ding through the pillar-plate to engage the yoke-lugf,substantially as specified.

4. In combination with a pivoted yoke F, theslide-bar i, substantiallyas described, a spring Z, and setting-lever Z, of a stem-arbor,

the stem-driven train, the winding-wheel, and

the dial-Wheels, substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
